Google do not, and literally never have "sold your personal information."
They deliver targeted advertising due to the information they have. That's the model. They make literally zero dollars a year selling personal information.
Source? Google is literally an online ad monopoly, and being sued for it. They did track and continue tracking users, and they sell data though their SSP, DSP, ad networks, ad exchanges they own.
Find the webpage where you can buy googles user data. Not where you can buy ad slots, but where you can buy the raw tracking data like data brokers sell.
